Election 2011: Worm won't use iPhone

A war of the worm is heating up as subterfuge, technophobia and low-income voters have cancelled plans for an iPhone-only rating of TV3's election debate.

The worm is a line on the bottom of TV screens which tracks responses to party leaders from undecided voters during debates. It is officially known as "the reactor".

Marcus Tarrant of Roy Morgan Research said the worm would return to screens next month after six years away following a controversial appearance in 2005. However, Tarrant's plan to roll out new technology for the device has had to be dropped for fear of inaccurate readings and "sneaky" interference.

Tarrant initially wanted all worm respondents to vote using their personal iPhones. But smartphone use in New Zealand is so low, and limited mostly to the wealthy, that an old-fashioned dial system has been brought back to represent a wider spread of voters.

Barely 5 per cent of New Zealanders own smartphones.

He said another problem was sneaky users "can get all their mates to connect and give the result they want.

"It's not an easy thing to do and get right. It's live TV. You don't get a second chance to get it right, and accuracy is critical."

TV3 has exclusive rights to use the worm. TVNZ corporate affairs spokeswoman Georgie Hills said TV One did not plan to use a worm-like device in any of its party leaders' debates.

He said politicians were disgusted when Peter Dunne repeatedly used the term "common sense" during a 2002 debate.

"The average senior politician wouldn't dream of using such a banal term. Most of us would have been too humiliated to use it. It was very manipulative."

Anderton suspected some leaders were receiving training on how to stimulate the worm, as they did in previous elections.

Peter Dunne said Anderton was "deluded". "I think that's ridiculous. I use the term frequently, worm device or no worm device."

Dunne said he received advice from strategists before the 2002 worm debate, much of which he ignored. "I think the worm is a huge distraction, even though I've been a beneficiary of it on a few occasions."

TV3 plans to roll out the worm for a Key and Phil Goff debate on November 21, in the week before the November 26 election. TV One will hold three debates. One will involve minor parties' leaders. The others will be between Key and Goff.
